      I have pfsense setup as a transparent firewall so I can protect a subset of devices.

      Our DHCP server is on the WAN side of the firewall and I want it to pass DHCP requests to the LAN

      I followed the fw rules from other posts but it still doesn't seem to work.  all the port 67 and 68 request get though but I receive a lot of 22X.X.X.X packets the get blocked and I'm not sure why these are required for the dhcp requests.

        Does your WAN interface get its IP address from DHCP? (Don't know if it makes a difference but it might).

        You don't say if you have the DHCP relay service enabled. I would guess that it should be. (My DHCP server is pfSense so I have no experience with DHCP relay.)

          I have tried it with both DHCP reply on and off.  I get the same issues.

          The WAN is a static IP Address.  Inside the subnet but outside the DHCP Scope.

          DHCP is obtained from the DHCP server on the WAN, not the pfsense box.
